" As of November 2013, about 100,000 of the approximately 1 million foreign students in the United States were approved to participate in OPT-an employment benefit that allows foreign students to obtain temporary work in their areas of study during and after completing an academic program. ICE is responsible for certifying schools; monitoring foreign students and schools, including their compliance with OPT requirements; and enforcing immigration laws for those that fail to comply. GAO was asked to review the management of OPT. This report examines the extent to which DHS has (1) identified and assessed risks associated with OPT, and (2) collected information and developed monitoring mechanisms to help ensure students comply with OPT requirements and maintain their legal status. GAO analyzed ICE regulations and policies and data on schools that recommend and foreign students approved for OPT, as of August 2013. GAO interviewed ICE and USCIS officials, including those from 7 of 26 ICE field offices selected based on factors such as OPT-related fraud investigations. Interview results cannot be generalized, but they provided insights about OPT risks. "
